Answer:

Median = 15

Mean = 22

Step-by-step explanation:

Median = first lets arrange the data type from smallest to biggest and select the middle number as it will be our median

1, 11, 14, 15, 31, 35, 47

the middle number is 15

so 15 will be our median

Mean = \frac{sum of all numbers }{total numbers\\} sum of all numbers divided by the number of values in the set

\frac{1 + 11 + 14 + 15 + 31 + 35 + 47}{7}

= \frac{154}{7}

= 22

so our mean will be 22

Rational numbers are those real numbers which can be written in \frac{p}{q} form.

Inverse property of multiplication is that property in which we write a number in reciprocal form .

Whole numbers starts from 0 and Natural numbers start from 1 and Integers contain both positive and negative numbers.

Therefore, Option 'B' and 'C' are correct.
